Abstract (en)

[origin: EP2821309A2] When the fuel supply to an internal combustion engine (22) has stopped due to a vehicle (1) starting to decelerate or the like, and the speed of the vehicle (1) is greater than a predetermined speed (Va), then a controller (14) causes a power generator (21) to operate in a first power generating mode. The controller (14) charges a capacitor (11) by using regenerative power that is output from the power generator (21) to supply power from the power generator (21) to the capacitor (11) via a DC-DC converter (13). When the stopping of the fuel supply to the internal combustion engine (22) is cancelled as a result of the engine revolution speed reaching a predetermined revolution speed (for example, an idling revolution speed) in conjunction with the speed of the vehicle (1) dropping to the predetermined speed (Va), the power generator (21) can be kept in the first power generating mode.
